The good news is that this increases elbow-shoulder room in the outside direction. If you lean slightly to the outside, there is a fair amount of arm/torso space over that doorsill between the seat and the door. This is good since there is no center console space to speak of between the seats, and traveling shoulder-to-shoulder with a passenger would be very cramped othewise.
However, leg room is not so lucky. There is a fair amount of length space under the dash to accommodate long legs, but the doorsill takes up much of the width making the foot area a bit cramped during long trips.
